Application filed December 22, 1904. Serial No. 237,941.

Be it known that we, ERNEST Genes, residing at 161i Montague road, Cape Hill, Smethwick, Birmingham, and THOMAS HENRY HrRs'r. residing' at Q2 Ash road, Saltley, Birmingham, England, subjects of the King' of Great Britain and Ireland. have invented certain new and useful Improvements in or Relating to Tires for Motor-Gars and other Vehicles, of which the following' is a specification.

This invention relates to tires for motorcars and other vehicles, the object beingto provide a tire having the resiliency of a pneumatic tire without its attendant disadvantages.

The invention consists in combining astrong inner elastic metal band with a stout outer rubber-and-eanvas arch-shaped cover capable of sustaining' strong' radial tension in Snell a manner that the cover is drawn tig'htly by its edges over the band toward the rim and held by suitable retaining' means, preferably wires and bolts. The rim is therefore held in suspension, the upper part of the cover being'in tension and offering' the requisite resistance to depression of the til'e.

Referring' to the accompanying' drawings, Figure l illustrates a' radial section of one form of tire constructed in accordance with the invention, while Fig'. 2 represents a section on the line A B of Fig. l.

A strong' steel band a (which may be perforated or corrugated for grip) of slightlyconvex cross-section and having' inwardlyturned edges I; is placed within an arch-shaped outer cover e of rubber and is embedded in several layers of canvas Z, the cover being of comparatively stout formation, especially at the tread portion. The layers of canvas Z are each coated with rubber and are continued on each side of the steel or other metal band to the edges ol the tire. Retaining-wires e are threaded through the canvas in the edges of the cover and hold the cover in place, being' kept in position by bolts f. The wires are preferably not endless, but have their ends guided in a tube. The rim l is provided with webs g, outside which the edges of the cover are placed when in position on the rim. Rings la, concentric with the w heels, with flanges m m peri'iendicular to the axis of the wheel in opposite directions, are fitted inside the rim l on each side and are held to the rim by nuts on the both sides of the rim pass through slots 7i: perpendicular to the plane of the wheel and are held in position at the inner end of said slots by the stepped wasl'iers t'. the smaller parts of which fit into holes bored partly or right through the rim, and it will be seen that the bolts f and rings /i will be held lirinly in position when the nuts are screwed home. Additional locking-nuts may also be litted to the bolts f, and the flanges m may also be bolted to the felly, if desired. Wrhere the wires n are not endless the edges can be contracted by the bolts f and any desired initial tension thus be put upon the cover.

lt will be understood that the rim is practically in suspension, the weight on the rim and the tendency of the lower portion of the tire to depression being' resisted by the upper portion of the cover, which is suspended from the strong band and is therefore in tension.

The cover may be drawn to and secured u pon the rim by any of the well-known methods employed for securing the arch-shaped outer covers of pneumatic tires.or it may be directly secured to the rim by screws, studs, bolts, or rivets; but in all cases au essential feature of our invention is the suspension of the wheel from the elastic metal band af by means of the strengthened cover.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent. is-

l. A vehicle-tire comprising' a strong steel band, an outer arch-shaped cover surrounding the same, the cover being' strengthened so as to be capable of resisting' strong' radial tcnsion, and having wired edges'` and eyebolts on the wires, substantially as and for the purposes hereinbefore set forth.

2. A vehicle-tire comprising a strong steel band, an arch-shaped cover surrounding'the same, said cover comprising an outer tread of rubber and numerous inner layers of rubbercoated canvas adapted to resist strong radial tension, Wires in the edges of the cover and In Witness Whereofwehave hereunto setI our eyeholts on the Wires adapted to pass through hands in presence of two witnesses. slots in the rim and through detachable Side ERNEST GREGG. ring-plates for the purpose of securely hold- THOMAS HENRY HIRST.
